UNirED sTATEs PATENT OFFICE. CHARLES SQL'rEsz, or NEW-,remy a y.

-To"allw'zmn. concern: I'

Be 1ty known 'that LCHARLES SoL'rsz, a subject of the KingofHungaryandfa V resident of the city of New York, borough of` .Manhattamin ,the county and State of New York,`have invented a new and ImprovedC-ultxvatnig-Machlne, of which the vfollowing is a full cl ear, andlexact description;

My invention relates to cultivatin chl-nes, Inymore particular objectbeing to producev certain improvements'in the type` of cultivatingmachine usually drawn by animals. 1

Reference is to be had to the accompany-- ing drawings forming a part ofthis speciication, in which similar characters of reference indicateAcorrespondingparts' in all gures. n `Iiigure 12"'s a side elevation ofmy harvest` ing machine complete, showing the framework mounted upon thewheels, the revoluble disks mova'bly mountedlnpon the rear of theframework, and fthe hoes ada ted lto be raised and lowered periodicallyor the pur pose of cutting the ground, this view further showing'-meansfor adjusting various parts; l

Fig;v 2 is a plan partly .broken away, and

showing the vrelative arrau ement of the disks and hoes, together withrmeans for actuating the'same, and furtherfshowing the means fordisconnecting the'gearing `from theimainshaft, so as to allow theoperating i f mechanism to"`be 'idle while the machine is draggedforward; Fig. 3 is asu'bstantially central vertical section, on the line3--3 of Fig. 2, showing` thereelfor lifting the disk cutters from thegroundand also showing` "the `eccentrics for operating 'the hoes, and

the screw mechanism, and gearingconnected operated screw, slideandpinion usedV forV disconnecting certain parts from the main and havingarc slots respectively drive.- -4

Wheels 5 and 6 rest jupon the ground and perform the oiice of vehiclewheels inasmuch as they support a portion of theweight of the entirestructure. 4These wheels arev `connected together byv a fixed' axle-7extendingentirely through the framework. Side plates 8, 9, each ofageneral arcuateform rammed sept. 29, 1908.

i concentric with the axle, (see Fig. 1) are connected together by aplate 10 extending practically across the entire machine. In front ofthese-plates is a compartment 11 covered by a door 12 which may beopened and closed at will. constitutes a box for tools used inconnection With'the various parts of the machine.

Braces 13 of metal are secured to the axle 7 and extend forwardly andupwardly, being provided with parallel portions 14, 15 which are lapped`upon opposlte 'sides of a central ybeam 16. This beam is provided witha head 17 through which passes a bolt 18. This bolt is provided with acom aratively long p ortion'18a and extends t rough "a wooden beam 19. vConnecting this wooden I beam,19 with the framework aretwo chains 20,and immediately in front of lthe wooden beam 19 is another woodenbea-m21. -'A clevis is shown at v22 and is provided ith a hook 22a. Thisclevis swings freely uon the bolt 18a. Braces 23 encircle the beams 19,21. and" hold the same rigidly together.

The'l beam :21 terminates in handles 24'.

which may be grasped by the operatori as he walks alongside the vehicle,the latter being in motion, so that by 'slightly turning the beam 21,and with it the beam 19,

all upon; the pin 18 as a center, he may guide the machine..

The front wheels are shown at 25'. The side'l .plates 8, 9 are providedwith down'- wai/dly lextending portions 26 (see Fig. 1), and connectinthese downwardly extending portions together are cross plates 27 28 (seelower ,right-hand corner of Fig. 3). The

'downwardly extending portions 26 togetherv constitute avertical-slideway, and slldably mounted therein is a cross bar 29, thiscrss bar being provided at its ends with lugs-30 (see Fig.- 1) whichextend directly throufgh the side plates 2 6, the latter being slottedor thisf purpose. v Y

Two revoluble screws 31 are each provided at thelower end with a pivot32 which wdrks lin the"l plate 27I as a bearing.lv Each screw"l isfurther provided with abead 33 rigid upon it'and extending above theplate 28 through4 .which the two screws 31 pass. Eachof these screws isprovided at its upper end wlth a wormwheel 34 which meshes with a worm35.

The compartment `11 These-'worms are controllable by handles-36 v andftothis vend both worms 35 and both handles36 are mounted rigidly u-pon asingle -Byl turning either handle 36 thei v may be.

shaft 36a' is rotated, the screws 31 are'turned,

and the bar 29 raised'or lowered, as the case The friction of the wormsand worm wheels is sufficientto retain the bar at any elevation to whichit may be raised or lowered.

A cover 9a of sheet metal is pivbtally mounted upon the framework at 9band is provided with a hood 37 extending to the l'ol'rea'r A`xed bracket38, integral with the plate 10. and `bent forwardly, and down-` wardlytherefrom, sup orts o ne'end of a revoluble shaft 39, the atter-beingprovided with a pivot 40 which works in the bracket 38 as a bea-ring. Alixedplate 41 supports the opposite end of the shaft39. This plate isvmounted rigidly upon a cross bar. 41, which extends practically thefull width of the machine and connects together the side plates 8 and 9.Mounted rigidly upon the shaft 39 is a ratchet wheel 42 which is engagedbya pawl 43, as will be understood 'from Fig. 2. A hand crank 44 ismounted rigidly upon the shaft 39. By turning the hand crank the shaftis rotated, and undesirable backward rotation is-prevented by the pawl.-By lifting the pawl by hand, the shaft may be turned backward.

.The shaft 39 isprovided with a threaded portion 45 which meshes with agear wheel '46, the latter being mounted rigidly upon vthe shaft 47,which is journaled in bearings the one just described and being rigidlycon-v v toothed sectors50, 54, being carried by the side plates 8 and 9.A guard 48 is mounted within the tool box and partially encompasses thegear 46, so as to pre` vent contact therewith of articles disposedwithin the toolbox, Rigidly mounted upon the revoluble shaft 47 is apinion 49 which meshes with a toothed sector 50 having a smooth portion51. This sector is rigidly secured to a sector frame 52,

which-extends on opposite sides of the plate 8 at the slot thereof andis movable relatively to the said plate, being adapted to swing upon thestationary axle 7 as a center. Upon the opposite side ofthe machine thearrangement is somewhat similar to that j ust' described. NA pinion ,53is rigidly mounted upon the shaft 47 and meshes-with a toothed sector54, this sector being substantiallylike nected with afsector frame 55which swings upon the shaft. 7. The side plates 8, 9, the plate l0, andthel cross bar 41a together practically constitute .the main frame.

the shaft7, are attheirouter circumference slidable in relation .to theside plates 8, 9. the

upper The journaled upon portions of the latter being of arcuateconformity and the sectors fitting against.' the under surfaces of theseportions. For this purpose eachof the two sectors. comfprises twoplatesspaced apart and disposed- "Mounted upon the sector fra'ne 55 arebearings 56, 57 (see Fig. 4) and disposed iu' ing journaled in thebearings 56, `'57.- lBy turning the screw the slide 58 i's raised orlowered, movingalong the slot 58,

as will be understood from Fig. 4. Aj

gear wheel 60 and a gear pinion -61 are both mounted rigidly upon thestubv` shaft 58a, and conseguently are .moved bodily whenever the slide;58 is moved bythe action of the screw Meshing with the pinion 61 is ayGear 62 (see Fig. l), this gear being mounte upon one end ofthe axle 7.A1. pinion 63 is mounted upon one end of a revoluble shaft- 64 whchextends practically across the` entire frame and is provided at itsother end with a balance wheel 64a.' .This shaft 64 ismounted upon theIsector frames 52 and 55 and carries four eccentrics 65 and extendingobliqnely ldownward from these eccentrics are eccentric rods 66 (seeFig. 3) 4which engage lugs 6.7- mounted upon swinging levers 68. 'Eachof these levers carries a hoe 69, and for this purpose is bent suby thelever 68, and then clamped rigidly in place by turning the set screw inthe opposite direction. The levers 68 are mounted upon *pivots 72extending between adjacent bars 73. These bars are of metal and restupon their edges, beingarranged in pairs, as indicated in Fig. 2, and attheir forward ends connected withthe cross bar 29. Each lever 68 isdisposed between a pair of .the bars 73, and each bar 73 is pivoted atits rear end upon a swinging bar 74, the latter being jou'rnaled upon abracket 75 supported rigidly upon the cross bar 41a.

A link 76 is pivotally mounted upon each bar 74 and extends rearwardlyand downwardly therefrom. A cutter disk 7 7 is mounted upon each link76, the latter heilig provided with a stub shaft 7 7'l for this purpose.I do not limit myself, however, to

this arrangement, for the reason that various changes may be made in theform of the link 76 and of the type of cutter carried by it. i So, also,the proportions of the several parts may be varied at will and thecutter disks may be made of different sizes and renderedinterchangeable.

.A pair offixed brackets 78 are mounted upon opposite sides of theframework. being secured directly to the forwardly bent por'- vtion ofthe cross bar 41a.- Disposed adjacent to these brackets are heads 79connected together `by rodsg80,{these rods: extendingl nearly the widthof the entire machine.. A- shaft A81 connects these heaolsf together andis journaled within the brackets 78. `The ro'ds Y80, shaft y:8l andheads7 9` togethergcn-I s'titute a.V reel. Partially wound 1 .upon this reelare chains` 82 which extend downwardly from lthe",` reel and engage `thelinks 76.v By

projecting abovethefreel. Ivmount a hand lever l86 upon this portion byaid of a pivot f 87. This hand lever is. provided with` a lug 88 whichengages the portionfS when the.

- hand lever 86 is 'thrown upwardly and toward the left, according vtothe view shown Fig. 1. A stop pin y88a supports the lever 86 when thelatter occupies its normal position.

In order` to turn the reel the operator igras'ps the free end of the'hand lever 86 and carries it upward, so Ias to carry the l-ug 88 intoengagement with the portion 85,of the. leirer 84.- Then, by pressingstill further in the same direction, lthe reel is turned and the links 76 and cutter disks 7 7 are raised to ana7 desired. extent.. A .hook 89lis disposedv very close to the path of travel of a portion 90 of thelever, this portion being made com.- paratively sharp. The loperator nowpresses the portion 90 1n. a lateral direction, so as to cause it toengage the hook89 and prevent backward rotation of the reel, and thuscause .the cutter disks to remain suspended at any desired heightpermitted by the limits of movement of the reel.

l/Vhenever the operator desires to change'L the general positionoccupied by the hoes, lne turns theJiand crank 44. This causes therotation of the rshaft 39 and the threaded portion 45 of the shaftthereupon turns the gear 46 and the shaft47 as above described. Pinions49, 53 being thus turnedand `meshing with the .toothed sectorsO, 54cause these sectors and the sector frames 52, 55 to turn upon thev shaft7 as a center, this action belng explained above. Since -the shaft v64ismounted rigidlyupon the sector frames 52, 55, it is movable bodilytherewith, and

consequently, when it is raisedA or lowered,

the eccentrics 65, .eccentric rods 66 (see Fig. 3) and levers 68 arelikewise raised or lowered. This movement is properly an adjustment asit is independent of the means 'for actuating the levers 68 in the senseof causing them to drive the hoes 69 into the ground. The operator, byturning the han- `elle 44, thus raises the rear ends of the levers lpreventing .the hoesground under any condition, or merely adjustingthe-:elevation :of the generalzone of activity of thel hoes, as desired.The chopping motionjis given to the vhoes 69` by the 66 upon theglevers6,8. v`The eccentrics are actuated by the rotation of the shaft 64, thisbeingaccomplished by the turni-ng pf the pinion,634 from the gear wheel60, whlch, as above "explained, is driven .along with the relatively tothev vehicle wheel 6 and always at the same time disconnect the pinion61 from the gear wheel 62. 4In doing this he destroys1 all operative vcol-mection from the vehicle wheel 6 to the vshaft 64 carryingtheeccentrics.- Such being the case, the motion ofthe levers 68 is stoppedcompletely. i

From the above description it will be seen that the cutter disks' may beraised or lowered independently of the hoes; that the hoes maybe raisedor lowered independently the gearing for operating thel hoes may beconnected with a wheel of. the vehicle and Idisconnected therefrom atwill. It will also be seen that the front ends of the levers `68 mayberaised and lowered at will.

v'bay the lsectors and sector frames, I provide ,a graduated scale' 90disposed in arcuate vide the sector frame 55 with a pointeri-91.

sitioriij of the pointer 91 and graduated scale 90, can` determine thecondition of elevation `or depression of the hoes.

My device is used as'follows: By aid of the hook 22a and clevis 22 .themachine is drawn along over the field, preferably by aid df animals. Theoperator walks along; side the machine and may at any time grasp eitherof the handles 24, By manipulating this handle he guides the generaldirection `of travel of the machine. l The cutter ldisks 77 are lowered,if he desires to'use the machineias a disk harrow, and the hoes arelowered and thrown into operation if he desires -to'chep the ground inaddition to the work doneby the cutterdisks. When the operator sodesires, he lifts the hoes or the cutters, or bothv the hoes and thecutters, out of en gageinent with the ground. He adjusts the depth ofcut of the hoes, or the depth of cut of the cutter disks, or the depthof cut of bothjthe hoes and the cutter disks, as above described.` Whenready to return.home, he
